Answer:

0.85

Step-by-step explanation:

A standard deck of cards has 52 cards. There are 4 10s and 4 Queens in the deck. There 8 cards that are 10s or Queens.

52 - 8 = 44

There are 44 out of 52 cards that are not 10s or Queens.

p(not 10 or Queen) = 44/52 = 0.85

Answer: 0.85

a tree casts a shadow 8 feet long. A 6-foot Man cast a shadow 4 feet long. The triangle formed by the tree and its shadow is sim

Elden [556K]

Answer:

12 feet

Step-by-step explanation:

Draw a diagram (see picture below). The tree and its shadow is one triangle, the man and its shadow is another triangle. We assume both are right triangles because people and trees stand vertical.

Create a proportion to solve. Put the missing value in a numerator.

Tree height / Tree shadow = Man height / Man shadow

$\frac{x}{8} =\frac{6}{4}$

Solve using cross multiplication. Multiply x by 4. Multiply 6 by 8.

4x = 48 Divide both sides by 4 to isolate x.

x = 12 Height of tree

The tree is 12 feet tall.

Directions are in the pic

Andrej [43]

Answer: 48

first you do 2x3 then divided by 2 to get one of the small triangles which is 6/3= 2 then double that to get the other small triangle so you have 2+2=4
then you find the area of the rectangle which you do 8+3 to get the whole of the length so it’s then 11x4= 44
then add the 4 from the two triangles and you get the area as 48
i think this is right

BRAINLIEST if -x = x -6 then x = A. -6 B. -3 C. 0 D. 3 explain please

Paul [167]

Answer:

D or 3

Step-by-step explanation:

The equation you are saying is

-x = x-6

If you move both x's to one side, you get

-2x = -6

From this, you can simplify by dividing by -2

x=3, or D.

Hope this helped!
